The motive for a shooting that killed a teacher and a student and wounded others at a Wisconsin school appears to be a “combination of factors,” a police chief said Tuesday as he appealed to the public to share what they might know about the 15-year-old girl who attacked a study hall before shooting herself.

Madison Police Chief Shon Barnes offered no details about a possible motive, though he said bullying at Abundant Life Christian School would be investigated.
